Anthrenus ( Florilinus ) loebli n . sp . ( Coleoptera , Dermestidae , Anthrenini ) from the Middle East

Anthrenus (Florilinus) loebli n. sp. (Coleoptera, Dermestidae, Anthrenini) from the Middle East.— A new species Anthrenus (Florilinus) loebli from Israel, Lebanon and Jordania is described, illustrated and compared with the similar species classified within the subgenus Florilinus Mulsant & Rey, 1868. The new species is characterized by oval eyes, eight–segmented antenna and subtriangular, occasionally triangular, scales on the dorsum. The yellowish/light brown scales are present on the anterior and terminal part of the elytra and create three irregular, transverse bands. Antennal segment eight are at least 4.8 to 5x longer than segment 7 in male, 2.1x longer in female. The new species is most similar to A. (F.) museorum (Linnaeus, 1761); A. (H.) fuscus Olivier, 1789 and A. (F.) flavidus Solsky, 1876. An identification key to externally similar species of the genus is given. The most distinctive taxonomic characteristics concern the male genitalia and antenna (in ratio of length of segments of antennal club) and are also described.


Introduction
Anthrenus carpet beetles are small and round.Their body is covered with colourful scales of various brown, tan, red, whitish and grey hues.The scales create different patterns (spots, transversal bands), especially on the pronotum and elytrae.These patterns are usually specific to a particular species, making them very useful in the identification process.

Material and methods
The size of beetles or their body parts can be useful in species recognition and thus, the following measurements were made: total length (TL, linear distance from anterior margin of pronotum to apex of elytra); pronotal length (PL, maximum length measured from anterior margin to posterior margin); pronotal width (PW, maximum linear transverse distance); elytral length (EL, linear distance from shoulder to apex of elytron); elytral width (EW, maximum linear transverse distance); F. Subgenus Florilinus; H. Subgenus Helocerus.
Moreover, the following abbreviations refer to the collections in which the examined material is deposited: JHAC.Private Entomological Laboratory and Collec� Private Entomological Laboratory and Collection, Jiří Háva, Prague-west, Czech Republic; MHNG.Museum d´histoire naturelle, Genève, Switzerland; MKCP.Marcin Kadej, Institute of Zoology, Department of Biodiversity and Evolutionary Taxonomy collection, Wrocław, Poland; NMGW.National Museums and Galleries of Wales, Cardiff, United Kingdom.
Specimens of the species described here are provided with a red, printed label with text as follows: holotype (or paratype, respectively) Anthrenus (Florilinus) loebli n. sp.J. Háva & M. Kadej det.2008.
The morphological structures were examined under a Nikon Eclipse E 600 phase contrast microscope with a drawing table attached, and a Nikon SMZ-800 binocular microscope; the samples were immersed in glycerin and exposed to transmitted light.After study, all structures were put back into plastic micro vials filled with glycerin under the appropriate specimen.Photos were taken with a Nikon Coolpix 4500 camera.
The terminology used in this paper follows that of Beal (1998).

Name derivation
The name of the new species is dedicated to the Mr I. Löebl, MHNG, taxonomist of Scaphidiinae.
Body convex, slightly elongate, covered by subtriangular, occasionally triangular, scales, mostly with 7-8, occasionally 5 more or less linear ribs; the apex of the scale body is truncate or concave and an apical lappet is present (fig.6).Head distinctly convex and oval eyes.Frons with median ocellus, covered with grey scales.Antenna 8-segmented, with 2-segmented antennal club (fig.3); antennal segments 1-6 light-brown, antennal club brown.Antennal segment 8 at least 4.8 to 5x longer than segment 7 in male, 2.1x longer in female.Antenna occupies whole cavity of antennal fossa.Antennal club occupies less than half of the antenna length in male and female.Antennal fossa completely open along lateral margin of the pronotum.Dorsal and ventral surface of integument brown, slightly punctated, covered with scales (figs.1, 2).Pronotum covered with mixed grey, yellowish/light brown (lateral margins, on the angles and central bottom apex) and dark brown scales (in the central part) scales.Elytra covered with mixed yellowish/light brown and dark brown scales.The yellowish/light brown scales are present on the anterior and terminal part of the elytra and create three irregular, transverse bands.The areas between bands are covered with dark brown scales mixed with single yellowish scales.Ventral surface grey except for visible sternites I-V covered with mixed grey and light brown scales; first abdominal sternite without stria.Legs brown, covered with grey scales on dorsal surface.Tarsus with two tarsal claws slightly curved.Male genitalia as in figure 4. Parameres U-shaped, covered with numerous short setae.Median lobe C-shaped, wide posteriorly, distal end of aedeagus strongly reflexed ventrally (figs. 3, 5).Pygidium lacking dark, subbasal, transverse, carina-like line; setae limited to apical area, occasional and rather randomly placed.

Variability
Occasionally, the dorsum of some specimens might be covered with grey scales only; in such cases, the dorsal patterns are absent.

Morfology of male genitalia
Aedeagus (median lobe) (in lateral view): S-like shape, slightly reflexed ventral F-like shape (A.museorum); C-like shape, slightly reflexed ventral (A.flavidus and A. loebli), Apex of aedeagus (lateral view): rounded (A.museorum/A.sordidulus); acute (A.flavidus and A. loebli), but bridge between paramers is relatively wide in A. flavidus but thin in A. loebli.All the species of apex of aedeagus are conical in shape (in frontal view), except A. museorum which is bubble-shaped.

Discussion
Many of Florilinus's species look similar externally thanks to the particular dorsal patterns.Main differences helpful in identification are found in morphology of male genitalia and form of antennae.For this reason the examination of the male genitalia and ratio of segment lengths of antennal club are crucial to confirm identification.
